The precipitation and effect of topologically close-packed phases in Ni . . . The precipitation of topologically close-packed (TCP) phases is the result of microstructure instabilities of Ni-based superalloys This review seeks to comprehensively collate all the available information on TCP phases in SX superalloys based on the latest findings
Formation of Topologically Closed Packed Phases in Nickle Base Single . . . The formation of topologically closed packed (TCP) phase was studied for a series of nickel base superalloys containing rhenium The alloys were found to form three types of TCP phases: rhombohedral mu, tetragonal sigma and a relatively unknown orthorhomic phase, P

The overview of the formation mechanisms of topologically close-packed . . . The nucleation and growth of topologically close-packed (TCP) phases in Ni-based single crystal superalloys (SCs) are controlled by composition, temperature, time, interface structure and stress The formation of TCP phases causes detrimental effects on the mechanical properties of SCs
Recovery of Creep Performance at Different Temperature and Stress . . . The DZ411 Ni-based superalloy bars (Φ16 mm × 220 mm) were directionally solidified using liquid metal cooling technology The nominal composition of the experimental alloy is listed in Table I All as-cast bars were subjected to a standard heat treatment (SHT): full-solution treatment at 1220 °C (1493 K) for 2 hours and air cooling (AC), primary aging at 1120 °C (1393 K) for 2 hours and AC
